Full title and description

IEEE Std 3102-2024 — IEEE Standard for Conservation Voltage Reduction (CVR) Data Collection and Management Procedures. This standard specifies procedures and requirements for electric utilities and stakeholders to collect, manage, clean, reconstruct, and verify data used to quantify energy savings and CVR factors from Conservation Voltage Reduction programs.

Abstract

IEEE 3102-2024 provides a standardized framework for measurement and verification (M&V) of Conservation Voltage Reduction (CVR) deployments. It defines data collection formats and sampling considerations, data-cleaning and reconstruction techniques for anomalous or missing values, detection of CVR operating status, treatment of load shifts, recommended archival/compression practices, and procedures to determine feeder- and system-level CVR factors as well as methodology selection for regulatory reporting and verification.

Scope

The standard specifies a set of procedures for CVR data collection and management to enable accurate estimation of CVR energy savings and CVR factors. It covers identification of CVR cycling schedule disruptions and required cleaning, archival/compression guidance, detection/validation of CVR operating status, identification and treatment of load shifts, reconstruction approaches for anomalous or missing data, procedures to determine CVR factor ranges and system-level CVR factors, data-adequacy checks, and selection of verification methodology based on data availability. Stakeholders include electric utilities, equipment manufacturers, software vendors, and regulatory commissions.

Key topics and requirements

• Definitions and terminology for CVR measurement, status flags, and events.
• Minimum data collection requirements (voltage, power, time stamps, device status) and recommended sampling/resolution.
• Data cleaning procedures: detection and handling of cycling schedule disruptions, outliers, and anomalous records.
• Data reconstruction techniques for missing or corrupted measurements to support reliable M&V.
• Methods to detect and validate CVR operating status and to identify load shifts that affect savings estimates.
• Procedures for calculating CVR factor ranges and aggregated system-level CVR factors.
• Guidance on archival compression rates, metadata retention, and data adequacy checks for regulatory reporting.
• Selection framework for verification methodologies tied to data quality and availability.

Typical use and users

Designed for electric utilities implementing CVR on feeders and distribution systems, the standard is used by utility analysts, distribution planners, measurement & verification teams, regulatory reporting staff, vendors of distribution-management and analytics software, equipment manufacturers, and consultants performing energy savings verification. It supports consistent regulatory filings and inter-utility comparisons of CVR program performance.
